11 Claims.

as hereinafter set forth.

One object of theinvention is to provide an improved mechanism of this character that is relatively simple in construction, permitting economical manufacture and assembly.

Another object of the invention is to provid an improved mechanism of this type in which provision is made to cause relatively rapid vibrations within a short range of movement to a vibrator member, whereby various physical effects may be carried out upon materials and therapeutic operations performed on human bodies to relieve nerve tension and/or congestions.

Another object of the invention is to provide an improved mechanism of this character in which the coil, core, the leads for the coil and the support for these parts constitute a unitary assembly adapted to be readily seated and secured in an enclosing member or support.

' A further object of the invention is to provide in an electro-magnetically operated vibrating mechanism, animproved mounting for the armature, whereby the latter is capable of readily responding to the current impulses the effect of which is to increase the number of vibrations imparted to the vibrator per unit of time, so that the vibrations will keepin step with the magnetic impulses and not lag behind, as is the case when using a heavy armature.

Other objects of the invention will be apparent to those skilled in the art to which my inventon relates from the following description taken in connection with the accompanying drawings, wherein Fig. 1 is a vertical section of a Vibrating mechanism embodying my invention (the variable resistance for regulating the current being shown diagrammatically) Fig. 2 is an enlarged view, partly in section` its upper end and preferably hollow and approximately conical in shape. The lower end of the casing is open to permit access to and inspection of parts hereinafter referred to. Interiorly of the casing, below its upper open end is an annular rib 2 forming a seat for a member 3 which is preferably cup-shaped and adapted to serve as a holder for a coil 4 and support for a core 5. The cup member 3 is formed of soft iron so as to provide a magnetic return circuit. rI'he bottom Wall of the holder 3 is formed centrally with an opening 6', preferably of polygonal shape, through which the body portion 5a of the core 5 extends; `'I'he body portion 5a terminates at a point below the plane of the rim of the side wall of the holder 3 for reasons which will later appear. The core 5 comprises T-laminations suitably connected to form a T-shaped core, the lateral arms or end portions of which are secured to the bottom of the holder 3, to provide magnetic contact therewith, in the following manner: 6, 6, indicate angle plates the vertical walls of which are secured to the opposite faces of a block 1. The block 1 is formed of non-conducting material, such as rubber compound, bakelite or ber. The horizontal walls of the plates 6, 6, are secured to the bottom of the cup-member 3. In the illustrated form of construction, as shown in Figs. 1 and 2, the arms of the core 5 are positioned on the block l between the vertical walls of the'plates 6, 6. The securing means for the vertical walls of the plates 6, 6, comprise two hollow tubular members 8, 8, preferably formed of metal extending through registering openings formed in such walls and the block 1, one end of each member 8 being flanged and its oppositeA end being threaded into the opening in the adjacent wall or riveted thereover. 'I'he horizontal wall of each angle plate 6, 6, is secured to the bottom of the cup-member by a tubular member 8 formed of metal and flanged at its outer end and threaded into an opening formed in the bottom of the member 3 or riveted thereover. The members 8 and 9 are made hollow from end to end so that the leads I0, II, for the coil 4 may extend therethrough from the coil to their terminals I3. The terminals preferably comprise A bolts extending through openings formed in the block 'l below the plates 6, 6. By preference, the leads I0, Il, are carried from the coil through the members 8, 8, respectively, and to the opposite sides oi.' the block and each is connected to one of the terminals I3, in a well known manner. Il indicates an armature supported by means of the shank I6 is formed with an inwardly extending threaded opening to removably receive a threaded stem I8 to the head of which is secured a device I9. When the parts above referred to are assembled, they are in xed relation so that the pulsations or reciprocatory movements of the armature are transmitted to the device I9, whereby the latter is vibrated.

The resilient member I5 comprises a plurality.

of relatively thin metallic disks I5a'\ preferably of the same diameter, their edge portions being supported on the rim of the cup-member. The disks I5a' are formed of suitable resilient material and arranged in face to face relation and secured together at their central portions by the nut I1, as already set forth. Throughout their remaining portions, the disks are disconnected so that in iiexing under the influence of the magnetic ux upon the armature I4, the outer portions of the disks are free to move or slide relatively to each other. This arrangement provides for the armature a support or mounting of high iiexibility so that retardation to the movement of the armature is reduced to a minimum; as a result, the armature vibrates rapidly per unit of time. ably rounded to provide edge contact with the resilient member I5.

The walls of the cup-member 3 may be formed with one or more openings 20 (preferably elongated) to admit air thereinto -for coolingpurposes. As shown in Figs. 2 and 3, the openings 20 are shown formed in the bottom and sides of the member 3. The vibrator device or member I9 may be comprise a at plate welded to the head for the stem I8 and covered with a layer 2I of suitable non-conducting material.

The upper open end of the casing I is closed by a cap 22. The side wall of the cap is preferably cut away to form a shoulder 23 arranged to engage the resilient member I5. By preference the cut away portion of the cap side wall is internally threaded to removably engage the external threads 24 on the casing I. The side wall of the cut away portion maintains the member I5 on andin concentric relation to the rim of the eupmember 3, whereas the shoulder 23 engages the member I5 to hold it against the rim of the cupmember 3. The cap 22 is formed with an opening through which the nut I1 extends.

The current for the coil 4 is supplied by AC mains 26, 26', in a conductor 21 leading through the side wall of the casing and connected to the terminals I3, one main (26) having interposed in it a cut-out 28 of any desired construction and the other main (26') having interposed in it a suitable variable resistance 29 to regulate the voltage, thereby regulating the strength of the magnetic impulses across the air gap between armature and core.

The side of the casing I may be provided with a detachable handle 30. The bottom of the casing may be provided with a pad of soft material, such as rubber, so that when the casing I is posifrom the vibrations set up in the member I9, being vportion of a core 5' extends. lerably of the same shape and construction as f th cu -member 3 is refer- The nm o e p p tom wall of the U-plate 34.

produced in or transmitted through such support is eliminated.

My invention may be used for various purposes. For example, the member I9 may be applied to various parts of the human body to relieve nerve tension, muscular troubles and congestion and to cause blood circulation. Where liquid, semiliquid and plastic materials containing relatively heavy ingredients have been stored for a period of time sufficient for these ingredients to, settle and become more or less hard, my mechanism may be used to recondition the material.

It will be understood that the vibrating member I9 may be removed and 'a member of a different shape substituted, depending upon the nature of the operation to be eiected.

Fig. 6 shows adifferent embodiment of the invention. In this view, 3|' indicates a casing having a transverse wall 32 and side walls 33 forming a chamber for a coil 4'. The wall 32 is formed with an opening through which the body shown in Fig. 4. The arms or end portions of the core 5' are held inmagnetic engagement with the wall 32 by a U-plate 34 having lateral arms which are secured to the wall 32 by tubular, metallic members 35. The outer ends of the members 35 are flanged to engage the lateral arms and their inner ends are riveted over. A screw 36 extends through the bottom wall of the U-plate 34 and an insulating block 31 and has threaded on it nuts 38a which rigidly secure the block 31 to the bot- The block 31 mounts suitable terminals 38, 38', to which the coil leads (which extend through the members 35) and supply wires 40 are connected. The wires 40 extend through a hollow handle 4I suitably 'connected to the casing 3 I The casing 3 I is shaped to provide a rear annular wall which forms a chamber 42 for the leads, wires and terminal block 31. 43 indicates a cover for the chamber A42, held in place by a ilanged screw cap 44 engaging the outer end of the screw 36.

I4' indicates an armature having a threaded stem I6' extending through a resilientv member I5', which engages the end wall of the casing 3|', the armature being secured to the resilient member I5' by a nut I1', and the stemof the armature removably carrying a vibrating member 9'. The resilient member I5 is held in position by a cap 22' threaded on the casing 3I'. The parts just described are preferably similar in construction to like parts shown in Fig. 1.

To those skilled in the art to which my invention relates, many changes in construction and widely diiering embodiments and applications of the invention will suggest themselves without departing from the spirit and scope thereof. My disclosures and the description herein are purely illustrative and are not intended to be in any sense limiting. Y
